Solution to foot pedal problem
I also found that after 2 years my GE Profile Trash Compactor (purchased in June '07), the pedal was hanging down on the left side. I searched the internet and called GE to no avail.
After a few attempts, I finally solved the problem by removing the screw on the left side and adding a metal "L" bracket, with the bottom of the L flush against the back of the front panel. That way, when you depress the pedal, the screw can't pop out of the metal it's attached to.
